Answer:
(x, y) ⇒ (x -2, y +2)
Step-by-step explanation:
Reflection across the line y = x+2 has the effect of interchanging x and y and translating by (-2, 2).
Reflection across the line y = x+4 has the effect of interchanging x and y and translating by (-4, 4).
The composition of these transformations is then ...
(x, y) ⇒ ((x +2) -4, (y -2) +4) = (x -2, y +2)

Answer:
, or in this case, 
Step-by-step explanation:
Assuming that Justine's score is represented by
and Meagan's score is represented by
, we know that
will always be the opposite of
.
To represent opposite, we put a negative sign before the variable.
This makes the current number, even if it's negative, the opposite value.
Let's test it out.
Since Justine's score is -7, substituting it into the equation makes it
. We know that two negatives make a positive, so
.
Now let's assume Justine's score is 7. Plugging it into the equation, we get
. That's the same thing as
, and -1 times 7 is -7.
Hope this helped!
